Double bellows



WILLIAM LILLIE, or EDWARDS, NEW YORK.

DOUBLE BELLOWS.

Specification of Letters Patent No. 4,066, dated June 2, 1845.

To all wiz-0m, t may concern `Be it known that I, WILLIAM LILLIE, of thetown of Edwards and county of St.

'Lawrence and State of New York, have invented or produced a new Plan ofDouble Acting Bellows; and I do hereby declare that the following is afull and exact description of the same.

Figure 1 represents the bottom of the bel lows made of two inch plank 2feet 3 inches in diameter. The square A, represents the orifice whichadmits the wind into the bellows between the lirst and second heads. Thedotted line around the square A shows the size of the valve and thedouble dotted line shows the side on which the valve is hung. The samemay be observed in Figs. 2, and 3.

Fig. 2 represents the second head which is placed at the distance ofeleven inches from the first, with the two hoops b b placed at equaldistances between, viz. from the first head to the first hoop 3 inches,hoop l inch, between the hoops 3 inches, second hoop l inch, then to thesecond head, 3

inches. The second head is made of 3 inch plank with an opening outthrough the entire diameter of the head, in the direction of the dottedlines C, C, C, C, and as represented in Fig. 5, by the parallelogram d,being 8 inches by 111i inches, the opening at E, is cut so as to meetthe last mentioned opening d, and admits the wind into the secondapartment of the bellows, between the second and third hea-ds. F, is anorifice to which is attached a leather tube, which is extended by 5 wirehoops which are bound with thin leather and sewed fast to the inside ofthe tube. This tube is fastened to the top of the second and bottom ofthe third heads by nailing, and serves to conduct the wind from thefirst to the third apartment of the bellows and discharges at Gr, inFig. 4

3. The tube is 5 inches in diameter and 13 inches in length, and asrepresented by Fig. 6 when extended.

Fig. 3 represents the third head with its intervening hoops as statedabove. The oritice at- I admits the wind from the second to the thirdapartments of the bellows. J is an orifice cut down into the plank andout at the side, in the direction of the dotted lines 7c, 7c, to conveythe wind into the pipe L, which conducts the wind into the re. Fig. 3 ismade of 3 inch plank.

Fig. 4 represents the top of the bellows,

with 1 or 2 intervening hoops as may be required, according to what workit is mostly to be used, t-he same rule may be observed with regard tothe distance between the hoops and heads throughout the bellows, and asshown in Fig. 7. y

Fig. 5 represents the side of Fig. 2, with t-he orifice d, which hasbeen described.

Fig. 6, has been explained in connection with Figs. 2 and 3. f

Fig. 7, represents the sides of the heads and hoops as they are placedin the bellows and as would be seen by looking directly into it, beforethe leather is put on, a; represents the valve at A, in Fig. 1, b represents the sides of the hoops, d the opening cut through F ig. 2, andshown in Fig. 5 at d, e the valve at E in Fig. 2. g and z', the valvesat Gr, and I in Fig. 3. The part marked tube shows the whole extent ofthe tube and the manner in which it is placed in the bellows. Thisfigure shows the bellows extended something near 11 inches more thanwhen the cramps are put on, and just the length required to be coveredwith leather. 1

N. B.- -The foregoing figures are all laid oftl a scale of l inches to afoot. And those to be described are from a scale of 1 inch to a foot, sothat if any omission is made in specifying it may be ascertained byapplying to the scale.

Fig. 8, is a left hand side view of the bellowswhen fit for use beingplaced a little in front of the post of the frame withthe eye elevated alittle above the lower end of the pole the letters M represent the framewhich is made of timber sawed 4 inches by 2, and is 4 feet 3 inches highand 2 feet 11 inches between the posts, length of the foot of the postis 2 feet 3 inches, from the bottom to the center of the plate marked tis 2 feet. From center of the plate f to center of plate N, is l foot 7inches. The plates marked N, are each l Vfoot long 2 inches wide andinch thick let into the posts of an inch and fastened to the posts withbolts and screws, into one end of which the bar to which the arms areattached are placed, and in the other end a rod is placed and fastenedon each end by screw nuts, to support the frame. O, represents the barmentioned and as shown in Fig. 9, being 2 feet 10gt inches between theshoulders and l inches from the shoulders to the arms, and 10 inches asmentioned above from the shoulder to the place of fastening on the poleas at P. Q the brace rod above named. R, a rod fastened to the top ofthe bellows by means of a plate, and running perpendicular through thebrace rod S to steady the top of the bellows. The rod S serves also tosupport the frame, being fastened with a nut and screw on each end. T,the arms that work the bellows, which are welded fast to the bar O, andis 5% inches from the bar to the eye in the arm as shown by the sideview of the arm. A U,

are the rods which are used to work the bellows in connection with thearms, being bent at the upper end so as to pass through the eye of thearms, and a nut put on the end to preventtheir dropping out of the eyes,as shown by Fig. l2, they are 2 feet 4 inches in length. The lower endsare fixed on to the .gudgeons which project from the second head asshown in Fig. 2, at h h 7L,

proper distance there are three cramps placed at equal distancesfromeach other, which are 16ginches in length from center to center ofthe bolt holes. They are fastened to the l and 3 heads by means of boltswith coarse screws cut of them and screwed into the heads.

Fig. 13 shows a side View of the cramps Y the openingat d Fig. 5. Z thepipe made of leather except a few inches at each 'end which should besheet iron, length of pipe 3%, feet. i the lower plates on the post ofthe frame 8 in. long by 2 inches wide and Jg in. thick and are let intothe posts and are fastened on in the same manner as the posts N N abovedescribed. The use of these plates is to hang the bellows and receivesthe gudgeons H, H, H, H, as shown in Fig. 3 which projects 4 inches fromthe p bellows to the plates and are driven into the wood 6 inches andare 7 inches apart and by these is the bellows hung pole which is 4 feet8 inches long 2 inches square at the lower end and tapering to l inchesat the upper end with a brace running from the lower side of the bar O(to which the pole is fastened) and running along the lower side of thepole 9 inches and fastened at each end with bolts and screws;

The particular advantages of the double acting bellows over the oldfashiened bellows are as follows, viz7 when the pole is borne down itraises the second head and discharges the wind from the second to thethird apartment through the orifice J in Fig. 3, and at the same timells the first apartment through the orifice at J in Fig. 1 and when thepole is raised it discharges the wind from the first to t-he thirdapart* ment of the bellows through the tube and discharges at Gr in Fig.3 and at the same time lls the second apartment through the opening at Ein Fig. 2 which causes a constant pressure into the upper part of thebellows and consequent-ly causes a constant and steady blast into the reso that there is no danger of sucking fire into the bellows as isfrequently the case with the old fashioned bellows and produces aheavier and steadier blast.

I- will also state that besides using it for i making it on an enlargedscale and rigging to go by water.

What I claim as myinvention and desire to secure by Letters Patent is-`The manner in which I have -combined the apartments of the bellows bymeans of the flexible tube, and the arrangement of the apertures andvalves as set forth.
